FIRELESS COOKER.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed February 4, 1909. Serial No. 475,956.

To all whom it may concern:

Be it known that I, P T R E. LITTLE, a citizen of the United States, residing at Day ton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Fireless Cookers; and I do declare the following to be a full, clear, and' exact description of the invention, such as will enable others skilled 'in' the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of-reference marked thereon, which form a part-of'this specification. I

This invention relates to new anduseful improvements in cooking utensils, and more particularly to improvements ,in a cover which is designed to prevent the heat from; escaping from the pocket or compartment in Wl'llClI the cooking vessel is placed after being subjected to. a certain amount of heat by being placed upon a stove or range. The cover also prevents colder air from entering said pocket or compartment. j

The apparatus in which the cover used is termed a fireless cooker in common parlance. It consists of a chest with one or more compartments or pockets there-in properly insulated so as to exclude air and retain eat. The cooking'vessel or vessels containing the article to be cooked are first placed upon a stove or range until the boiling point is reached or approximately so; said vessel or utensil is then removed from the stove and is placed in one ofsaid compartment or' compartments where the heat is retainedto complete the cooking. By thus prolonging the cooking operation after the vessel is removed from proximity to the fire, much of the flavor is retained and the article so cooked is rendfiied more palatable and otherwise desira e.

Preceding a detailed description of the in-' 'vention, reference is made to the accompanying drawings, of which- Figure 1, is a vertical sectional elevation through one of the pockets or compartments of a tireless cooker having a cooking utensil therein and my improved cover inclosing said pocket or compartment. Fig. '2, is an enlarged section of a portion of said cover adjacent to the edge. I

in a detail description of the invention, similar reterence maracters indicate QQITGfi spending parts.

For the purpose of describing my inven ition, I have illustrated one pocket or compartment which is preferably of circular form and is inclosed by a metallic lining 3. Ar-

ranged onlthe outside of this metallic lining and completely inclosing it, is a wall 4 of substantial thickness and consisting of any suitable insulating material which is calculated to confine the heat within the pocket, such material for example, as asbestos, mineral Wool, etc. Inclosing this wall of insulation It will be observed that the metallic lining -3 extends out of the pocket or com artment r are the walls 1 of the chest or casing'which is laterally, and upwardly against 1; e upperv I ortion of the chest terminating immediately below the cover 2. The laterally-extended portion of the metallicelining incloses the upper surface or. edge of the insulation 4 and provides a fiat smooth surface which has an Important arrangement with the interior cover'which will now, be described. The interior cover 8 is constructed of wood and is of circularform, across-the upper side thereof-and extendingfrom one edge to the other, is a handle port'on 9 in the middle of which is inserted a rub er ti 10 to be again referred to. On the inner si eof the-cover 8 and extending around near the circumference thereof, is a resilient bead 12 constructed of flexible material, preferably cotton-rope, and

inclosed bya sheathing 11 of textile fabricpreferably cotton. The two elements, to-wit:

the bead 12 and its covering 11, combine to form a substantial packing, which, when the cover is in position, seals the pocket or compartment. The casing 11 is united to the cover 8 by extending portions 11 thereof parallel with the plane of the cover and unit ing them in any suitable manner at such points. Inclosing the space within this pack- 1n ring and fitting snugly against the inner side thereof, isan asbestos disk 13. Lying against the outer side of this asbestos disk 13 is a metallic disk 14 of substantially the saine diameter and size, and both of which disks are detachably secured to the'in'ner side of.-

the cover 8 by means .of a winged screw 15. The metallic disk 14 preserves the asbestos disk from the disintegrating efiects of any 1 11o moisture arising from the vessel or utensil within the pocket or compartment. Furthermore, by means of this detachable connection, the metallic disk 14 may be removed I pressible tip extended from the upper side of trom the cover for the purposes of cleansing said cover, said tip being engaged. by the without subjecting the packing or sealing ring to water or the like.

5 designates a form of cooking utensil within the pocket or compartment and hav ing a lid 6 which is held on the top of said utensil by suitable fastening devices 7. The weight of the wood cover 2 engaging the rubber tip 10 exerts a suitable pressure upon the lid 8 to compress the packing ring or bead 11 or 12 against the ii at surface provided by the laterally extended portions of the metal?" lining 3, and thus eil'ectually seal the pocket or compartment from any escape'of the heat therein caused by the heated utensil, and from any admission of air to the pocket. will be understood the utensil or vessel 5 with its contents is removed from the stove or range after brought to the boiling or baking point, and is placed in the pocket or compartment; the cover 8 is then placed above the pocket and the outer cover 2 is closed. The heat within the utensil is thus caused to practically maintain a given temperature unl til the contents have been thoroughly cooked. The natural flavonof the article is thus preserved while the possibility of scorching or burning the contents or reducing the liquid to an improper condition is avoided. It will be understood that the casing or chest may be of any suitable length to provide as many of the pockets or compartments as may be necessary, and other details of construction may be varied without departing from the spirit of the invention which consists in the construction and advantages of and due to the cover 8 as hcreinbefore set forthf I claim:

1. In a fireless cooker, a casing providing a pocket or compartment in which to place the heated utensil, the space within said casing above said pocket being increased in diameter to provide a horizontal ledge or shoulder at the upper terminal of said pocket, a cover having a sealing bead on its lower side adjacent to. its circumference, said bead consisting of resilient material inclosed within a fabric secured'to the under side of the cover, a asbestos disk inclosed by said sealing bead, a metallic disk inclosed by said sealing bead' and lying against the asbestos disk, said asbestos'and metallic disks being detachablynnited to the cover, and a comcover of the casing when the latter is closed and whereby the sealing bead is tightly *es'sed against the horizontal ledge or shoulder surroumling the upper end of the pocket or compartment.

2. In a tireless cooker, a main casing having a cover and providing a pocket or compartment, the space within said casing above said compartment or pocket being of greater diameter than said compartment or pocket, a heat--insulating material in. which said pocket or compartment is provided, a me tallic lining for said pocket or compartn'lent, /said metallic lining extcn ding laterally in the form of a leg or shoulder at the upper termin al of the pocket or lftlllipilll ment and pro- 1; viding a flat annular surl'ace surrounding the l mouth -ol' the poctzct or r -om artmcnt, a cover having a scaling bcad of an elastic 1 nature secured to its inner side and adapted l to engage the llat annular surl'acc surroundfing the mouth of the pocket or compartment, at detaclnible metallic disk secured to g the coverand the circumference of which is l inclosed by the annular sealing head, a hand I piece'attached to the upper side of said cover, and a compressible tip secured to said handpiece an d adapted to beengaged by the cover I of the casing and whereby the sealing bead is tightly compressed to seal the pocket or compartment.

3. In a tireless cooker, a circular cover adapted to seal a compartment or pocket containing a heated vessel, said cover having a sealing bead on one side. thereof adjacent to itscircumference, said sealing bead consisting of a flexible strand which is inclosed by fabric casing united to the cover, an asbestos I disk adjacent to the cover on one side and t the circumtcrencc of which is incloscd by the sealing bead, and a detachable metallic disk adapted to shield the asbestos disk and the adjacent suriaceol' the cover from the heat within the com nn-tmcnt or pocket, said metallic disk being detachable [or the purposes of cleansing.

In testimony whereof I allix my signature, in presence of two witnesses.
